Abstract

The invention belongs to the technical field of plant cultivation and in particular relates to a method for planting Suaeda salsa on a saline-alkali land. The method comprises the following steps of selecting and processing seeds (1), preparing the land (2), applying fertilizer (3), watering (4), trenching (6), broadcasting (7) and irrigating (8) and harvesting. By the use of the method, provenance merit factor and bud ratio can be guaranteed and improved; saline and alkaline of the soil can be reduced; survival of seedlings of the Suaeda salsa and final output can be improved; great ecological effect and environment protection can be improved; saline-alkali land and beaches can be greened and beautified; and utilization rate of the saline-alkali land can be improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for planting Suaeda salsa in saline-alkali land. Background technique [0002] my country has a vast area of ​​saline soil, and the reserve cultivated land resources are mainly saline soil. With the increase of population, the decrease of cultivated land resources and the increasingly prominent contradictions such as ecological deterioration, the development and utilization of salinized wasteland to alleviate the pressure of food security has attracted much attention. Salinized wasteland is a natural landscape in arid areas and an important reserve cultivated land resource. For a long time, people have used traditional technologies (building irrigation and drainage facilities, washing salt with water) to reduce the salinity content of the soil. This process is not only costly, but also As the scale of cultivated land expands, there are no more water resources ...
